Article Synopsis
- Cannibalism is a common behavior in animals, often driven by survival needs like food scarcity or overpopulation, but it can also have drawbacks like spreading diseases and lowering overall health.
- In primates, it can occur alongside infanticide or when mothers eat their deceased infants (known as filial cannibalism).
- This report details the first observed case of infant cannibalism in brown capuchin monkeys, where a mother and her surviving child consumed parts of a stillborn baby, potentially as a way to recover from the energy loss of pregnancy.
Article Synopsis
- Foraging in seasonal environments poses cognitive challenges for primates, with brain size linked to fruit-based diets.
- This study examined how fruit distribution and preference influenced foraging choices among three primate species with varying frugivorous habits.
- Results showed that primates favored clumped fruit distribution, particularly the more frugivorous species, indicating food type and distribution may play a significant role in cognitive evolution.
